As a low-paid employee at The Underground Ball Factories (TUBF), you are placed at the workstation no one wants to run: "The Sorter". It is not a popular station amongst your co-workers, mainly because the factory produces an unbelievable amount of red and blue balls to be sorted at a very unstable pace, but also because of Ukko; a caveman who's lived in the cave for 2000 years before TUBF placed a ball-factory in his home. Being as annoyed as the next man would be when someone places a ball-factory in his home, Ukko does whatever he can to distract you from doing your job and make your boss fire you.

You hold in your hands a switch button that controls a ramp. This ramp guides the balls either to the left or right, depending on the switch control of course. Your job is simple: Control the ramp with the switch button, so that red balls are guided into the red pipe, and the blue balls are guided into the blue pipe. You earn 10 points for each ball you sort correctly, but misguided balls will make your boss angry, and if your boss gets too angry you will loose your job.
